Guys,
I just got news from RaceChip Germany that they finally finished testing on their GTS Black for BMW G30 530i.
It is a simple plug-n-play piggyback tuning module.
I have been selling RaceChip product in the past 3 years and it is a popular product in F15/F16 X5/X6, F85/F86 X5M/X6M, and F90 M5 community.
Feel free to comment or PM for questions.
Here is the video of their testing.
